Video captures moment barge slams into sailboat carrying campers in Biscayne Bay

Security camera footage reveals the moment a barge rammed into a sailboat carrying five kids and a camp counselor on board — killing two girls and critically injuring two more in Miami Beach.

The footage — taken from across the Biscayne Bay — shows the small sailboat with bright colored sails floating in place in the water Monday morning between Hisbiscus and Monument islands.

The 60-foot barge then collides with the 17-foot Hobie Gateway, going over the small boat until the neon colored sails sink out of frame. The crash killed Mila Yankelevich,7, and Erin Ko Han,13. Two other campers, ages 8 and 11, were critically injured. A large crane could be seen on the barge that was being pushed by a tugboat.

Another camper, a 12-year-old girl, and the 19-year-old camp counselor were rescued.

The U.S Coast Guard, which is investigating the crash, said at a Tuesday press conference that the agency conducted an alcohol test on the captain of the tug boat and will be investigating whether the tug and barge’s crew were properly licensed to be on the water.
